Description
本発明は、ホウ素を含有せず、化粧品分野および家庭用洗浄製品における使用に適した、精製カチオン性グアー(purified cationic guar)の調製手順に関する。 The present invention relates to a procedure for the preparation of purified cationic guar, which does not contain boron and is suitable for use in the cosmetic field and household cleaning products.
本発明の手順によって得られるカチオン性グアーは、酸性および塩基性pHの両方で水に可溶であり、したがって、極めて広い幅のpHを有する水溶液において粘性を発現するという技術的に有用な特性を有している。さらに、上記カチオン性グアーはそれを化粧品分野に適したものとする純度を有する。 The cationic guar obtained by the procedure of the present invention is soluble in water at both acidic and basic pH, and thus has the technically useful property of developing viscosity in aqueous solutions having a very wide pH range. Have. Furthermore, the cationic guar has a purity that makes it suitable for the cosmetic field.
カチオン性多糖類は天然由来の誘導体であり、そのコンディショニング特性により、工業的な添加剤として多用されている(すなわち、これらは、これらが適用される基材、一般的には紙、皮膚、髪または布(fabric)の特性を改善する)。 Cationic polysaccharides are naturally derived derivatives that are widely used as industrial additives because of their conditioning properties (ie they are the substrates to which they are applied, typically paper, skin, hair. Or improve the properties of the fabric).
この特性は、これらを、シャンプー、ヘアコンディショナー、クリーム、パーソナルケアまたはハウスホールドケア洗浄剤、および、布にソフトな肌触りと帯電防止性を付与する軟化剤の調製のために、産業上有用なものとする(例えばConditioning Agents for Hair & Skin, Ed. R. Schueller and P. Romanowski, Marcel Dekker Inc, NY, 1999を参照)。 This property makes them industrially useful for the preparation of shampoos, hair conditioners, creams, personal care or household care cleaners, and softeners that impart soft touch and antistatic properties to the fabric. (See, for example, Conditioning Agents for Hair & Skin, Ed. R. Schueller and P. Romanowski, Marcel Dekker Inc, NY, 1999).
そのコンディショニング能力のほか、これらの多糖類の、これらが溶解された溶液を増粘し、そのレオロジーを調整する能力は産業上有用である。 In addition to its conditioning ability, the ability of these polysaccharides to thicken the solution in which they are dissolved and adjust their rheology is industrially useful.
特に、カチオン性ポリガラクトマンナン、中でもグアーガムのカチオン性誘導体は、これらが調合されたシャンプーで洗浄した髪の湿潤時および乾燥時の櫛通り性(combability)の改善について最適な結果を示している。 In particular, cationic polygalactomannans, especially cationic derivatives of guar gum, have shown optimal results in improving the combability of wet and dry hair washed with shampoos in which they are formulated.
化粧用調合物(cosmetic formulation)において、明確に加えられたものでも制御されたものでもなく、予測されたものでもなく、バッチごとに変化し得る物質の存在が、例えわずかな量であっても、前記調合物の調製中に、相分離や粘度の変動などの問題を生じさせ得ることはよく知られている。 In cosmetic formulations, neither explicitly added nor controlled, nor anticipated, the presence of substances that can change from batch to batch, even in small quantities It is well known that problems such as phase separation and viscosity fluctuations can occur during the preparation of the formulation.
さらに、ここ数年の間に、化粧品の製造に用いる原材料の毒性に特別の注意が払われるようになった。例えば、EC指令76/768/EECおよびその後の改訂は、消費者の健康を守る目的で、化粧品用の原料における特定の物質の存在を制限するか、禁止している。 Furthermore, during the last few years, special attention has been paid to the toxicity of the raw materials used in the production of cosmetics. For example, EC Directive 76/768 / EEC and subsequent revisions limit or prohibit the presence of certain substances in cosmetic ingredients for the purpose of protecting consumer health.
特に、上記指令は、EEC指令67/548/EECによる付属書IIに列挙され、発がん性、変異原性または生殖毒性として分類されている、カテゴリーCMR1、CMR2またはCMR3に関する複数の物質の化粧品における存在を禁止している。同じEC指令76/768/EECによれば、必ずしも成分として存在しないが、原材料の生産過程に由来する不純物としてのみ存在する他の物質(付属書IIIに列挙された物質)の存在は、量的制限の対象となっている。 In particular, the Directive is listed in Appendix II by EEC Directive 67/548 / EEC and presents in cosmetics a plurality of substances relating to categories CMR1, CMR2 or CMR3, classified as carcinogenic, mutagenic or reproductive toxic. Is prohibited. According to the same EC Directive 76/768 / EEC, the presence of other substances (substances listed in Annex III) that are not necessarily present as components but are present only as impurities from the raw material production process is quantitative It is subject to restrictions.
したがって、化粧用調合物、および、皮膚と直接接触する調合物、例えば、家庭用洗浄製品などに用いるには、消費者の健康のため、および化粧品の製造に関連する技術的問題のために、グアーのカチオン性誘導体が不純物を可能な限り有しないことが根本的に重要である。 Therefore, for use in cosmetic formulations and formulations that come into direct contact with the skin, such as household cleaning products, for consumer health and due to technical problems associated with the manufacture of cosmetics, It is fundamentally important that the cationic derivatives of guar have as little impurities as possible.
さらに、化粧用調合物または家庭用洗浄剤のpHは、落屑防止剤の明らかに酸性のpHから染髪料の明らかに塩基性のpHまで多種多様である。したがって、これらの製品には、あらゆるpHにおいて水に可溶な成分を用いるのが産業上好都合である。 Furthermore, the pH of cosmetic preparations or household cleaners varies widely from the apparently acidic pH of desquamation inhibitors to the apparently basic pH of hair dyes. Therefore, it is industrially convenient for these products to use components that are soluble in water at any pH.
カチオン性グアー誘導体は、その使用が防水紙の製造において言及された70年代初頭から知られている(US 3,589,978参照)。 Cationic guar derivatives have been known since the early 70's when their use was mentioned in the manufacture of waterproof paper (see US 3,589,978).
カチオン性グアー誘導体の化粧品における最初の使用は、グアーのカチオン性誘導体が、通常の洗浄力のほかにヘアコンディショニング特性を有する、いわゆる「ツーインワン」シャンプーの製造に使用された1977年に遡る(US 4,061,602参照)。 The first use of cationic guar derivatives in cosmetics dates back to 1977 when the guar cationic derivatives were used to make so-called “two-in-one” shampoos, which have hair conditioning properties in addition to the usual detergency (US 4,061,602). reference).
化粧品に用いられるカチオン性グアー誘導体は、グアーヒドロキシプロピルトリモニウムクロリドのINCI名で知られており、化学的にはグアー2−ヒドロキシ−3−(トリメチルアンモニウム)プロピルエーテルクロリドである。 Cationic guar derivatives used in cosmetics are known by the INCI name of guar hydroxypropyltrimonium chloride and are chemically guar 2-hydroxy-3- (trimethylammonium) propyl ether chloride.
その合成は、例えば、引用したUS 3,589,978特許に記載されているように、塩基性触媒(水酸化ナトリウムなど)の存在下での、2,3−エポキシプロピルトリメチルアンモニウムクロリドまたは(3−クロロ−2−ヒドロキシプロピル)トリメチルアンモニウムクロリドの、グアーのヒドロキシル基に対する反応を必要とする。 Its synthesis is described in, for example, 2,3-epoxypropyltrimethylammonium chloride or (3-chloro-2, in the presence of a basic catalyst (such as sodium hydroxide) as described in the cited US 3,589,978 patent. Requires reaction of -hydroxypropyl) trimethylammonium chloride to the hydroxyl group of guar.
試薬2,3−エポキシプロピルトリメチルアンモニウムクロリドは、発がん物質CMR2として分類される。試薬3−クロロ−2−ヒドロキシプロピルトリメチルアンモニウムクロリドは、対応するエポキシドより毒性は低いとしても、CMR3に分類され、アルカリ媒体中で2,3−エポキシプロピルトリメチルアンモニウムクロリドに変換される。 The reagent 2,3-epoxypropyltrimethylammonium chloride is classified as a carcinogen CMR2. The reagent 3-chloro-2-hydroxypropyltrimethylammonium chloride is classified as CMR3 even though it is less toxic than the corresponding epoxide and is converted to 2,3-epoxypropyltrimethylammonium chloride in an alkaline medium.
US 3,589,978に記載されているところによると、反応はイソプロパノール、メタノール、エタノールおよびtert−ブタノールなどの溶媒中、30〜60℃の温度で行うことができる。同特許の例Aにおいて、反応の終わり、および、アルカリ過剰の中和の後、未反応の4級試薬を除去すべく、生成物を乾燥し、粉砕し、メタノールで洗浄する。 According to US 3,589,978, the reaction can be carried out in a solvent such as isopropanol, methanol, ethanol and tert-butanol at a temperature of 30-60 ° C. In Example A of the same patent, after the reaction and neutralization with excess alkali, the product is dried, ground and washed with methanol to remove unreacted quaternary reagents.
US 3,589,978には、最終生成物中のカチオン試薬(2,3−エポキシプロピルトリメチルアンモニウムクロリド)の残留量について何ら報告されていないが、メタノールはそれ自体毒性物質であると見ることができる。 US 3,589,978 does not report any residual amount of cationic reagent (2,3-epoxypropyltrimethylammonium chloride) in the final product, but methanol itself can be viewed as a toxic substance.
US 4,031,307には、塩基性触媒を含む水と水溶性溶媒との混合物中で固形グアーとカチオン化試薬とを反応させることによる、二相系におけるグアーのカチオン性誘導体の調製が記載されている。反応の後、得られた生成物は、遠心またはろ過によって分離し、好ましくは、合成に用いた水−溶媒混合物による第1の洗浄と、同じ溶媒のより無水の形態による第2の洗浄とにより精製する。 US 4,031,307 describes the preparation of a cationic derivative of guar in a two-phase system by reacting solid guar with a cationizing reagent in a mixture of water and a water-soluble solvent containing a basic catalyst. After the reaction, the product obtained is separated by centrifugation or filtration, preferably by a first wash with the water-solvent mixture used for the synthesis and a second wash with a more anhydrous form of the same solvent. Purify.
US 2001051143には、反応の終わりに85重量%のイソプロパノール水溶液による第1の洗浄と、純粋なイソプロパノールによる第2の洗浄とを含む、グアーのカチオン性誘導体の調製が記載されている。US 2001051140には、反応の終わりに、85%イソプロパノール水溶液による2回の洗浄を含む、グアーのカチオン性誘導体の調製が記載されている。 US 2001051143 describes the preparation of a cationic derivative of guar comprising a first wash with 85% by weight aqueous isopropanol at the end of the reaction and a second wash with pure isopropanol. US 2001051140 describes the preparation of a cationic derivative of guar comprising two washes with 85% aqueous isopropanol at the end of the reaction.
これらの刊行物のいずれにおいても、得られたカチオン性グアー誘導体に存在する不純物の種類や量は言及されていない。この不純物は、カチオン性グアー誘導体が化粧用原材料として用いられる場合に、最終的な化粧品の一部になるものである。 None of these publications mentions the type or amount of impurities present in the resulting cationic guar derivative. This impurity is part of the final cosmetic product when the cationic guar derivative is used as a cosmetic raw material.
現在市販されているカチオン性グアー誘導体の大部分は、水および溶媒での洗浄による精製に関連する困難性および負担を回避するため、例えばCA 2,023,324に記載のように、事前にホウ酸塩で架橋した生成物を水のみで洗浄することにより精製されており、反応相にはホウ砂が添加されている。こうして得られるカチオン性グアー誘導体は、少量のホウ素を含む(ホウ酸化(borated)グアー)。 The majority of currently marketed cationic guar derivatives are pre-cross-linked with borate to avoid the difficulties and burdens associated with purification by washing with water and solvents, for example as described in CA 2,023,324. The product thus obtained is purified by washing only with water, and borax is added to the reaction phase. The cationic guar derivative thus obtained contains a small amount of boron (borated guar).
ホウ酸による架橋の目的は、ホウ酸アニオンを介して多糖鎖の間に結合を形成し、生成物を水に不溶性にすることである。
これらの結合は塩基性pHで安定しており、したがって、かかる条件では、生成物を副産物から洗い出すことができる。
酸性条件ではホウ酸塩による結合が取り除かれ、生成物は可溶であり、その増粘およびコンディショニング特性を発揮することができる。
The purpose of crosslinking with boric acid is to form bonds between the polysaccharide chains via borate anions, making the product insoluble in water.
These linkages are stable at basic pH, so that under such conditions, the product can be washed out from the byproduct.
In acidic conditions, the borate linkages are removed and the product is soluble and can exhibit its thickening and conditioning properties.
ホウ酸塩による反応は、pH変化により可逆的である。したがって、生成物が酸性のpHで予め可溶化されていたとしても、それをアルカリ条件に戻すことにより、調合物の粘性を変化させ、その結果、製品の質を変えることができる。 The borate reaction is reversible with pH changes. Thus, even if the product has been previously solubilized at an acidic pH, returning it to alkaline conditions can change the viscosity of the formulation and, consequently, the product quality.
したがって、ホウ酸化カチオン性グアー誘導体の限界は、ホウ酸塩で処理した生成物が7を超えるpHで可溶ではないため、酸性または弱酸性pHで使用される製品にしか適用できないことである。
さらにまた、ホウ酸誘導体がカテゴリーCMR2の生殖毒性物質として分類されていることを認識しなければならない。
Thus, the limitation of borated cationic guar derivatives is that they can only be applied to products used at acidic or weakly acidic pH because the borate treated product is not soluble at pH above 7.
Furthermore, it should be recognized that boric acid derivatives are classified as category CMR2 reproductive toxicants.
染髪料は、最も大きく拡大しているホームおよびパーソナルケア分野の1つである。これらは通常、8を超えるpHで調合され、したがって、これらにホウ酸での架橋により精製したカチオン性グアー誘導体を調合することはできない。 Hair dyes are one of the most expanding areas of home and personal care. They are usually formulated at a pH above 8, and therefore they cannot be formulated with cationic guar derivatives purified by crosslinking with boric acid.
一般的に水溶液中で7.5を超えるpHを有し、通常皮膚用の軟化剤およびコンディショニング剤を含有する固形石鹸バーの調製は、非ホウ酸化カチオン性グアー誘導体の使用に関して大いに関心を集めている別の分野である。 The preparation of bar soap bars, generally having a pH above 7.5 in aqueous solution and usually containing skin softeners and conditioning agents, has attracted much interest regarding the use of non-borated cationic guar derivatives. Is another area.
一般に塩基性pHを有し、場合によっては皮膚保護機能を有する共調合剤(co-formulating agent)を有利に含有する脱毛クリームの調製および布用粉末洗浄剤の生産は、非ホウ酸化カチオン性グアー誘導体を用いることができるさらなる調合物である。 The preparation of a hair removal cream and the production of a powder cleaning agent for fabrics, which advantageously contains a co-formulating agent which has a basic pH and in some cases has a skin protection function, is a non-borated cationic guar. Further formulations in which derivatives can be used.
出願人は今回、あらゆるpHで可溶であり、ホウ素を含まず、それが成分として用いられる化粧用調合物の安定性または毒性学的特性に影響し得る他の不純物の含量が少ない、精製カチオン性グアーの調製手順を見出した。 Applicants now have purified cations that are soluble at any pH, free of boron, and low in other impurities that can affect the stability or toxicological properties of the cosmetic formulation used as an ingredient. A procedure for preparing sex guar was found.
